Product Overview
Diethylenetriamine pentaacetic acid (DTPA) LR is a highly effective chelating agent widely used in laboratory settings for its ability to bind metal ions with exceptional stability. This white to off-white powder is formulated to meet LR (Laboratory Reagent) grade standards, ensuring high purity and reliability in analytical applications. Its molecular structure, featuring five carboxylic acid groups, allows it to form stable complexes with a broad range of metal ions, including calcium, magnesium, and transition metals, making it indispensable in processes requiring precise metal ion control. The compound exhibits excellent water solubility, facilitating easy preparation of aqueous solutions for experimental use. Its low toxicity profile and chemical stability under standard lab conditions further enhance its suitability for routine and specialized applications. The LR grade designation guarantees minimal impurities, reducing the risk of interference in sensitive assays or reactions. Whether used in titration, spectrophotometry, or as a masking agent, DTPA delivers consistent performance, ensuring reproducible results across multiple experimental runs. For optimal storage, keep the powder in a tightly sealed container in a cool, dry place, protected from moisture and direct sunlight. This product is compatible with most standard lab glassware and plasticware, though it is advisable to verify compatibility with specific materials in highly sensitive applications. Its versatility extends to various pH ranges, though performance may vary depending on the target metal ion and experimental conditions. As a staple in analytical chemistry, DTPA LR provides researchers with a dependable tool for achieving accurate and reliable outcomes in their work.
